Aven de Rogues

The network includes an uninviting widened constriction, Un short meander, Un meander, Un meander high up with a 3 m climb, Un low passage, Un narrow passage at the top of Un small step, a small chaotic chamber, Un low passage among blocks, Un muddy crawl, a narrow damp gallery, a spacious gallery dotted with puddles, a constriction between blocks, a perpendicular gallery and a constriction on the right.

A small stream of water falls into Un P15. The spacious gallery is dotted with puddles up to Un lake equipped with a clear line at -170; on the other side, a constriction between blocks gives access to a perpendicular gallery. A second lake, also equipped with a clear line, is crossed. The Grand Collecteur network comprises a succession of watered shafts and Un collector that ends at Un sump at -226.

From the entrance to -128 (dining room): Un P21 is followed by an uninviting widened constriction opening onto Un P16. Un short meander gives access to Un superb P14. Un meander followed by Un P12 and Un pendulum (window high up) allow access to Un P20. Follow the meander without descending Un blind P8 to reach two P10. Then follow the meander high up (3 m climb); 40 m further on, Un 8 m step allows access to the dining room (-128), which is Un important crossroads.

Réseau Sud: enter Un low passage that opens into large chambers. At the low point of the first chamber, take Un narrow passage at the top of Un small step. Un meander, Un R4 and Un P8 lead to a small chaotic chamber. Un low passage among blocks leads to Un P22. After Un R5 and Un P15, Un P15 is reached where Un small stream of water falls. At its base, Un muddy crawl leads to -223.

Horizontal network: from the dining room, descend Un R7 followed by Un R3. Then the discovery gallery splits into a narrow damp gallery. The gallery widens and Un branch on the left is left aside. The gallery continues spacious and dotted with puddles up to Un lake equipped with a clear line at -170. On the other side, a constriction between blocks gives access to a perpendicular gallery. Turn left and cross Un second lake, also equipped with a clear line. At the end of the gallery, four networks can be reached: réseau du laminoir, réseau de la Cordelle, réseau des Nîmois, réseau de la taupe éthylique.

Grand Collecteur network: at the end of the discovery gallery, a constriction on the right gives access to a succession of watered shafts and Un collector that ends at Un sump at -226.
